From dbc9c14c92a5acf450d07868a735ac8cd6ec5b90 Mon Sep 17 00:00:00 2001

Subject: [PATCH] lapi/pidfd: adding pidfd header file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The newer Glibc already provided wrapper for the series pidfd syscall,
so let's include the header file conditionally.
# rpm -q glibc-devel
glibc-devel-2.35.9000-31.fc37.ppc64le
# rpm -ql glibc-devel | grep pidfd
/usr/include/sys/pidfd.h
To get rid of compiling error from fedora-rawhide:
tst_safe_macros.c: In function ‘safe_pidfd_open’:
tst_safe_macros.c:135:16: error: implicit declaration of function ‘pidfd_open’ [-Werror=implicit-function-declaration]
135 | rval = pidfd_open(pid, flags);
| ^~~~~~~~~~
Upstream-Status: Backport [https://github.com/linux-test-project/ltp/commit/dbc9c14c92a5acf450d07868a735ac8cd6ec5b90]
